  • the data storage unit 55 stores a set value of the sound volume of the warning unit 54 , a setting of a type (e.g., continuous sound or intermittent sound) of sound of the warning unit 54 , a setting of preliminary warning, and a set value of continuous time of the preliminary warning.
  • the setting of the preliminary warning is a setting for determining whether the preliminary warning for immediately attracting attention is performed or not when the burglary sensor 43 detects occurrence of burglary. This preliminary warning is generated after the occurrence of burglary for only a relatively short time before a serious warning is generated to attract attention without a delay time, so that a threatening function which more quickly discourages the burglar can be achieved.
